Abstract
Provided are polyethylene glycol drug conjugates of general formula (I), (II) or (III) and pharmaceutical compositions and a use thereof. The conjugates are formed by combining low molecular weight polyethylene glycol with 2-4 drug molecules. The conjugates can interact with receptor dimers or polymers, thereby improving the in vivo distribution of the drug, changing the oil and water distribution coefficient, enhancing the pharmacological activity, reducing the blood-brain barrier permeability of the drug, and improving the bioavailability of the drug.
